KI 209–style NAV indicator: rotating OBS / compass card, CDI (lateral) and GSI (vertical) bars, TO/FROM flags, nav/ GS warning flags, and a fixed reference arrow. When navDataValid is false, lateral/vertical deflections and flags are zeroed/hidden per the component’s visibility rules.

Installation

npm install @openattitude/steam-ki209-generic @openattitude/core vue

Peers: vue ^3.5. installPanelMath() required (Math.clamp on deflections and flags).

Export

Ki209
